strip the entire striking mechanism of the bell is mounted.

An arch 12 is secured to riveting over the bridge; An opening is formedin this bridge by pressing the metal outward and forming a flange 13.This flange is of suitable length to provide a bearing for apinionsupport 14, having a recess 15 for the reception of the spindle 6.A pinion 16 is secured to a reduced part of the pinion-support 14, whichis headed over to secure the pinion in To all whom it may concern:

Be it known that I, PHILIP C. ARNOLD, a and a resident of East Hampton,in the county of Middlesex and State of Connecticut, have invented a newand Improved Bell, of which the following is a specification.

The improvement relates more especially to the class of door-bells orthe like, although it is not specifically limited to such class and theobject of the invention is to provide means or a mount for the mechanismwherethe bridge, as by by the parts of the latter may be readily selace.cured in place without liability of breaking The bridge 10 is extended,as at 17, (see the part to which they are secured; and a iurdotted linesin Fig. 1 of the drawings,) and a ther object of the invention is toprovidea simple construction of mechanism and means for securing theparts thereof. One form. of device in the use of which these objects maybe attained is'illustrated in'the accompany ing drawings, in which-Figure 1 is a top or plan embodying my invention, the gong beingremoved. Fig. 2 is a view in central section through the base and a partof the support to which the bell is secured.

In the accompanying drawings the numeral 5 denotes a door or the like towhich the bell is to be ai'fixed; 6, a spindle extending through thedoor and which may be operated, as by means of a thumb-turn 7. Thespindle is especially at its ends, to fit corresponding openings orrecesses in the thumb-turn and in a portion of the bell mechanism, sothat rotation of the thumb-turn shall be imparted to such mechanism.

The bell-base is formed of cast-iron open at its center and providing arim 8. This may be of any suitable form, that herein being shown asround, and on the inside of this rim ears 9 are formed integral with thebase. A bridge 10, of wrought or other comparatively tough metal, issecured within sockets 11 in these ears. In the preferred form ofconstruction this bridge is secured in place in the process of casting,the bridge being inserted in the mold and the metal allowed to run aboutand inclose the ends thereof. This bridge consists of a single piece orstrip of metal extending across the opening bounded by the rim, and uponthis single plate or i post 18 is secured in this extension, as byheading the end of the post over. A small pinion 19 and a larger pinion20 are rotatably mounted on this post, the larger pinion meshing with apinion 21, secured to the strikerarm 22, bearing strikers 23, that inthe rotating movement of the arm strike against a lug on the gong in theusual manner for the purpose of sounding the bell.

The operation of the device will be readily understood from the abovedescription.

view of a bell-base present time is obtained by riveting the severalparts which are to be secured in place, and most of the bells in use atthe present time have the parts thus secured. It is desirable that thebell-bases shall be constructed of cast metal, and where the posts andother parts are secured in place as by riveting it will be readilyunderstood that great care must be exercised not to break thecomparatively brittle metal of which the base is composed. A furtherelement of waste and loss in riveting parts to a cast-metal base resultsin the effort to straighten posts and other parts after they have beensecured. In the majority of instances it will be found after a post hasbeen riveted that it must be straightened, and this straighteningprocess frequently results in the breaking out of the base around thepost and a consequent loosening of the latter. In the use of myinvention, the posts and other parts being secured to a metal which willyield, the posts may be readily straightened, and the loss in theassembling of the parts is thus much reduced. The bridge of wroughtmetal is also of advan- The cheaper construction of bells at the theends which pass through stood that other tage in preventing cracking ofthe casting as it cools after the metal has been poured. Skilled laboris therefore required to properly secure the parts to the cast-metalbases with I little breaking of parts and consequent waste. By thewithin invention it will be seen that a metal having comparatively toughcharac l teristics is secured to the base without blows to fracture theparts.

While I have shown and described herein abridge cast into the base, itwill be undermeans of securing the base may be employed which will notnecessitate the delivery of blows to properly secure the bridge, andsuch are contemplated as within t e invention.

. That I claim as my invention, and desire 1' to secure by LettersPatent, is-

' mechanism.

a 1. In a bell, a base including a rim of cast metal, a bridge formed ofa single plate of tougher metal extending across the opening bounded bythe rim and secured thereto by means of an opening with a partprojecting thereinto, bell-striking mechanism mounted on the plate, andmeans for operating the 2. In a bell, a base including a rim formed ofcast metal, a bridge formed of a single plate of tougher metal extendingacross the opening bounded by the rim and secured thereto by means of anopening with a part projecting thereinto, one of said parts being formedin the process of casting, bell mechanism secured to said plate, andmeans for operating the mechanism.

I 3. In a bell, a base including a single plate formed of acomparatively tough metal, and a rim formed of cast metal with socketscompletely inclosing the ends of said bridge, 1' striking mechanismmounted on the bridge, and means for operating the striking mech anism.

4. In a bell, a base including a rim formed of cast-iron, a bridgeformed of a tougher metal extending across the opening and securedthereto by means of an opening on one part receiving a projection fromthe other part, a gong-post supported by said bridge, a gong secured tosaid post, bell-striking mechanism mounted on the bridge, and means foroperating the mechanism.

5. In a bell, a base including a rim formed of castiron, a bridgecomposed of a tougher metal and including a single plate extendingacross the opening bounded by said rim and secured thereto by means ofan opening on one part receiving a projection from the opposite part, anarch secured to said bridge, a post secured to said arch, a gong mountedon the post, bell mechanism supported by the bridge, and means foroperating the mechanism.

6. In a bell, a base including a rim formed of cast-iron, a bridgeformed of a single'plate of tougher metal extending across the openingbounded by the rim and secured to the latter by means of a projection onone part located within an opening in the opposite part, said bridgehaving a hub bearing formed by the metal forced from an openingtherethrough, a pinion bearing mounted within said hub, a strikersupported by the bridge, connections between said striker andpinion-bearing, means for operating the pinion-bearing, and a gongsupported by the bridge.

7. In a bell, a base composed of cast-iron and including a rim, a bridgecomposed of a single plate of tougher metal extending across the openingbounded by the rim and secured thereto by an opening on one partreceiving a projection on the opposite part, a hub-bearing formed insaid bridge by metal forced from an opening therethrough, an archsecured to the bridge, a pinion-bearing mounted in said hub, means forrotating said bearing, a gong-post secured to said arch, a strikersupported by the plate, connections between the pinion-bearing andstriker, and

a gong secured to said post.
